Angular JS 1.x:

The AngularJS is an open-source JavaScript-based framework that is used for developing Single-Page Applications (SPA). It was first released by Google in the year 2010 it is maintained by Google and a community of individuals and corporations. Some of the features of Angular JS are as follows:

  • It is based on the model–view–controller (MVC) and model–view–View-Model (MVVM) architecture.
  • The current stable version is 1.6.10.
  • Angular development code is written in JavaScript
  • It extends the HTML supports by adding tags, attributes, and expressions.
  • It provides event handling in a simpler manner as well as provides a built-in template and routing.
  • Some of the important features are Form Validation, Dependency Injection, Animations, etc

Angular 2:

The Angular 2 Framework is completely re-write from its original Angular 1 or Angular JS and this is completely re-write from the scratch using the Typescript language. It was released in September 2016 by Google. Some of the features of Angular 2

  • It is a faster, Modern, and highly scalable JavaScript framework
  • By default Angular 2 applications are mobile-friendly.
  • It supports many languages such as ES5, ES6, Typescript or Dar to write Angular 2 code.
  • It is based on Component-based architecture.

Why not Angular 3?

The Angular 2 Framework is a single repository. That means each package is downloadable with the @angular/package-name convention. For example @angular/core, @angular/compiler, @angular/HTTP, @angular/router, etc.

Angular Versions and Versioning

The Angular Development Team skipped Version 3 and the reason behind this is a version mismatch. As you can see in the above image, all the package names were assigned with version 2, but the router package by mistake was given version 3. Therefore, the Angular Development team skipped this version and directly jumped to version 4 to maintain compatibility with Angular Router’s version.

Angular 4:

The Angular 4 was released in March 2017 and it is not completely re-write from Angular 2. In Angular 4 there are few minor changes and some new features are added.
For most of the applications, this release is backward compatible with 2.x.x. Angular 2 and was released in March 2017 and there is no major change in Angular 4 from Angular 2. Angular 4 is not the complete rewritten form of Angular 2. In this release, the angular team has laid emphasis on making the app faster. Some of the features of Angular 4

  • By the new changes, it reduces the size of the generated code up to 60%.
  • The animation moved to a separate package called @angular/animations.
  • It provides faster compilation.
  • It supports for email validator i.e. with Angular 4, we don’t require writing a pattern to validate email.
  • Provides better support bug fixes alert.
  • It supports if-else statements.

Angular 5:

The Angular 5 was released in November 2017 and this version doesn’t bring any significant change from Angular 4. In this version, lots of new features, as well as many new improvements, are done. Some of the features of Angular 5

  • The HTTPClient API was introduced by Angular 5 which is used to simplify the HTTP library for Angular applications. This library is much more secure, efficient and faster than the earlier HTTP library as well as it also provides some additional features such as typed requests, testability, and response objects.
  • Support for Internationalized Number, Date, and Currency Pipes. The earlier versions of angular were fully dependant on the browsers to get the number, date and currency format which resulted in inconsistency for users.
  • The Build Optimizer was introduced which optimizes the build size and improves the application speed.
  • Type checking in templates
  • Improved Compilation. The compiler uses TypeScript transforms, a new feature of TypeScript 2.3 available onwards.
  • Zone speed improvements
  • New Router Lifecycle Events

Angular 6:

Angular 6 was released in May 2018 and this version was released along with Angular CLI 6 and Material 6. Some of the features of Angular 6

  • Updated Angular CLI (Command Line interface): With Angular 6, some new commands are added such as ng-update which is used to migrate from the previous version to the current version, ng-add which is used to quickly add application features.
  • Updated CDK, Component Development Kit: This supports to create custom UI elements without the need of the angular material library.
  • Multiple Validators: This basically used to validate the user input on a form.
  • Usage of RxJS, a reactive JS library
  • Tree Shaking on Services: Now the tree shaking can be applied to services to remove the unused code. That means it will remove the code from the final bundle if that code not being used or not referenced in the application.

Angular 7:

Angular 7 was released in October 2018. The following are some of the features of Angular 7.

  • CLI (Command Line Interface) Prompts: In Angular 7, the CLI prompt has been modernized to version 7.0.2. With the new and updated version of angular CLI, when the user executes common commands such as ng add @angular/material or ng new, it will prompt users.
  • Application Performance: The Angular 7 application is much faster as compared to the previous versions of the angular application. This version does not aim only on making the application small but makes the application small too as much as possible.
  • Bundle Budget: Now in Angular 7, the developers can set up a budget limit of their bundle size. A default setting of the bundled budget has 2 MB as the lower limit and 5 MB as the higher limit. The developer can also change these settings as per need. Reduction in bundle size improves the performance of the application.
  • Angular Compiler: The new angular compiler offers an 8-phase rotating ahead-of-time compilation. The NGCC (Angular Compatibility Compiler) will convert node_modules compiled with Angular Compatibility Compiler (NGCC), into node_modules which appear to have been composed with TSC compiler transformer (NTSC). Also, the Ivy rendering engine can use such a “legacy” package due to this compiler change.
  • Drag and Drop: With this feature, now the user can drag and drop the items on the list to reorder the list. It also allows the transfer of elements between the lists. Using the CDK drag handle, a user can customize the drag area as per requirement. Multiple handles apply on a single item if requires. As per the user’s command, the item may move along the X-axis or the Y-axis because the movement of drag and drop restricts along an axis.
  • Virtual Scrolling: The Scrolling feature was introduced in the previous angular 6 while Angular 7 comes with virtual scrolling. The Virtual scrolling allows the users to bind a list of elements even it’s too long in small packets. As per the scroll movements, the data will be supplied into packets at the user end.

  • Faster testing, Better debugging
  • Improved CSS class and style binding
  • Improved type checking, build errors
  • Improved build times, enabling AOT on by default
